Ping runs as a low priority service so it is not realistic to measure response time using ping.

So between the last "Internet" router (bbnet2.lax.pnap.net) and > broadvoice's edge router, there is an additional 16% loss. Just an update after about 12 hours of data--the data above was worst case. During off-peak hours in the middle of the night the packet loss at my ISP was effectively zero, and only 3% along the way to broadvoice, with a 75ms round-trip time. Broadvoice edge-router still reports 28% packet loss though, and an additional 30ms RTT increase for this last hop. So I even more strongly suspect (or just really hope) they are preferentially discarding non-RTP traffic in favor of voice traffic. I did discover that the multi-second outages are at my local ISP, not at Broadvoice--for some reason Sprint BBD can take up to 4 seconds to respond to a ping, so something is really wrong there--but is there a way to do this type of testing in a more rigorous and controlled fashion? -Johnathan _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
